This invention relates to improvementsin wheel mountings for land vehicles and more particularly the invention relates to wheel mountings for all types of vehicles, implements or trailers being propelled by an external source of power.

An important object of the invention is the provision of a wheel mounting for a land vehicle which will enable the latter to be supported on four ground engaging Wheels,'all of which have their axle supported rigid with respect to the vehicle frame or chassis, and yet the said wheels will be arranged with respect to each other so that the vehicle may be turned in the same manner as an ordinary two wheeled vehicle.

A further object of the invention is to provide a wheeled mounting for a land vehicle which will permit the latter to be used in irrigated districts, or the like, and wherein the vehicle will travel over ditches, or other irregularities, without any of the wheels dropping into ditches or other similar depressions.

Other objectsv and advantages of the invention will be apparent during the course. of the following description.

In the accompanying drawings forming a part of this speciiication and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevation view of one form of wheel support embodying this invention,

Fig. 2 is a top plan view of the structure shown in Figl, and,

Fig. 3 is a side elevation view of a modified form of Wheel support.

In the drawing, wherein for the purpose of illustration is shown the proposed embodiment of the invention, the numeral 5 designates in its entirety the frame or chassis of a land vehicle of the general type which is adapted for being pulled or pushed over the ground by means of an external source of V power, such as an automobile, a tractor, etc. For the purpose of propelling the vehicle frame 5, the frame has attached to one end thereof a draft coupling 6 which may be of any desired shape or style.

It is to vbe understood that the frame 5 may be supported by relatively large wheels which extend above the plane of the frame. Such a type of wheel is illustrated in Fig. l. It also is to be understood that the frame 5 may be supported by relatively `small wheels which will not extend above the floor line of the vehicle frame.v Such a type ofy wheel is illustrated in Fig. 3, the small wheels being associated with the vehicle frame 5a.

Returning to our'discussion of Fig. 1', it will be seen that the frame 5 has suitably secured thereto axles Kupon which are rotatably mounted the Wheels 8. These relatively large wheels 8 extend above the plane of the floor kof the frame 5. It also will be noted that the wheels are arranged in stagf gered relation with respect to each other and overlap to a considerable extent. In fact, the wheels 8 are intended to be overlapped to the greatest extent possible, just so sufcient clearance is provided between the peripheries of the wheels and the axles 7; It also will be noted that the distance between the axles 7 is less than the diameter of either wheel. f

In the figure best illustrating the vehicle including the frame' 5a, the wheels 9 are supported on axles 10. Itis to be understood that these axles 10 are positioned as closely as possible to each other and that the wheels 9 are oset or staggered with respect to each other and overlap to the greatest extent prac-- tical.

It will be noted that the axles 7 and 10 do not oscillate or pivot with respecty to the frames 5 and 5a respectively. It is intended that these axles be non-pivotally mounted with respect to the frame whereby none of the wheels will articulate for steering purposes. y The wheels are so closely positioned to each 90 other that a vehicle equipped with the same may be pivoted in substantially the same manner as an ordinary two wheeled vehicle may be pivoted. This arrangement of wheels will enable a vehicle to be supported by four wheelsinstead of two and yet the benefits of a four wheeled support will be obtained. It also will be noted that when a vehicle frame, of the type illustrated in the various iigures, is'attached to a tractor or the like, by means Y' l e i V1,751,010` f of adraft attachment 6, the vehicle may be .c v; pulled over irregular surfaces, such as irrigated fields, Without any of the Wheels drop- Y Vj' 'f ping into a ditch, or the like. Fig. 1 discloses 51 a vehicle'frame passing over a ditch and being supported by one pair of axially alined Wheels Whil'ethe remaining pair of Wheels'are out of'contact with theground dueto the `fact Y i -fthat they are being carried overa ditch. 0rV
